Lambchop With A Renault Axis Here...

Ok I don't really understand this, so bear with me here...

I take it what you're saying Alex is the duty of the injectors has an impact on the severity of the shifts? So if the injectors are at a low duty, you get sloppy shifts?

So if I was going to stick with 98, I'd want to run standard or under 500cc injectors to keep them at 80-90% duty?

First I'm hearing of all this, so just trying to get my head around it. You're running 600-odd cc Deatschwerks, right Alex?

Hey mate. It's the base fuel schedule, not the injectors. But it's related. You want to run close to the capacity of the injector, but also with a margin of error. For example, if you have a 98 car running 1000cc but tuned to 220 kw or so, using 50% duty, then gearbox will be shit. It just won't run decent line pressure, because it does not reach the area in the table where the gearbox firms up. Now, if you run 1000cc and are on e85 and your are running big power, then you see 80% duty, a higher bfs and the car will access the good part of the table. Run a injector suitable for your power level.

I'm on 600cc, don't know what duty cycle, but I'd guess about 60% at most.

Sorry, another thing is the best way to do it would be to plug in your piggyback and with the stock injectors and boost check what base fuel schedule the cars sees at a stock k fuel multiplier. Then drop in injectors, wind up boost and try to get as close as possible to the original base fuel and retain safe tune. Note that your ecu will never change the calculated load table, don't think you could ever change it, but I don't now what effect that table has.

Nice! :yes:

Does your car really run out to 6800 rpm or is there a slight calibration issue with that dyno & your car? And is your sig up to date? Is your 'tune' what the std ECU is giving you with the mods you have done, or do you have something else?

standard ecu, and yes its up to date.

i know that my ecu is different to yours because i dont have speed cut at 170km/h like everyone else so i'd assume AUTECH have played with a few things on the ECU.

as for my redline i'll have to double check that, but yes he bounced it off the limiter LOL

as far as i have been lead to believe i didnt have an LSD but my nice 11's down the road (private road) tell me otherwise.........

also yes Leon, my engine rev's till 6800RPM.

Just tried mine, shows a single spinner in the diagram. I've used this before but never figured out this function. Thanks Dunc.

You'd better get in touch with them, to let them know they need to update your stats with a f**k off big turbo!

I punched mine in; and it doesn't specifically say that it has an LSD (which it does), but if you click on "Final Drive, Rear" it displays the exploded diagram of the Viscous LSD diff assy.

You should also get 'Spec Code: DIFF6' which, if you hover over, says 'Viscous LSD' (or at least thats what mine does)

Only shows ETC2 in the spec code. Oh well.

Pretty easy way to tell - stick your jack under the diff, lift, and turn a wheel. The other side of my car turns the oppo way, Craigs with the LSD turns the same way.

You can do 11-sies with an open, but if you have a hint of lock on, it'll do the inside.

throwing some idea's together for modifing my axis front bar............

basically steal the R35 grill insert and make my own version of that to suit the axis lines and steal the audi's design of the side air vent sections and marry them all together.......... i've got a vision in my head so i know what it's gonna look like but putting it on paper is another story LOL

    • So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?      
    • Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.
    • I did not realise this, I'll contribute more and earn my stripes and retry later. 
    • I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
    • Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!
